CENTRIFUGAL HYDRAULIC ENGINE.

Specification of Letters Patent.

Patented July 16, 1912.

Application filed July 17, 1911. Serial No. 638,984.

To all whom it mayconcern:

Be it known .that we, MAURICE GOUDARD and MAROEL MnNNnssoN, engineers, citizens of the French Republic, residing at 39 Rue Fouguet, Levallois-Perret, Seine, in the French Republic, have invented certain new and useful Improvements in Centrifugal Hydraulic Engines, .ofwhich the following is a specification.

This invention relates to centrifugal hydraulic engines for water and other liquids and has for its principal object to simplify such engines and consequently to facilitate their construction and increase the uses to which they can be applied.

The invention consists essentially in constructing the aforesaid engines with a rotary drum adapted to receive liquid and provided on one at least of its faces with a central aperture, and with a fixed system of pipes extending through said aperture and so located that when liquid is supplied throu h the pipes this liquid is first conducted into the said drum and then con ducted away. I

The invention consists moreover in adapting apparatus of the type described to act as radiators or as pumps. It also includes certain methods of carrying out the construction hereinafter described.

It will be clearly understood from the following description and the annexed drawing which are given merely by way of example.

Figure 1 of the drawing is a transverse section of an apparatus constructed according to theinvention associated with an internal combustion engine provided with'a water jacket, the apparatus being so constructed that it forms at the same time the radiator and the fly wheel of the aforesaid engine. Fig. 2 shows the same parts in side elevation with portions broken away.

According to the invention, in building a centrifugal hydraulic engine, in 'place of adopting one of the constructions hitherto customary which constructions are more or less complicated. the following method is adopted. A rotary drum, is provided and consists of a single drum, such for example as shown at a, and having in one of its faces an aperture a or else this may consist of -a drum such for instance as that shown at (1 having an aperture on each of its faces, or again it may consist of a certain number of drum-like elements each of which elements may be similar to one of those just- By reason of'this construction the manufacture of apparatus of this kind can be greatly simplified as there is not a single joint to be made while it is possible to adapt the apparatus to various purposes, and in a particularly advantageous manner especially for radiators, in which case the subdivision of the drum and the use of the separate tubes a is especially desirable. In this case moreover it is preferable to embody at the same time one or more of the following features. The aforesaid drum should be constructed of aluminium or some similar material. This renders it possible to rotate apparatus of the class under consideration at a much greater velocity with the same power than ordinary engines on account of the low specific weight of these materials, the consequence being that if such an engine is used as a radiator its efiiciency is very greatly increased. It is desirable to adapt to the surface of the aforesaid drum vanes 0, and in particular vanes curved inward and so formed that when the drum is rotating they produce the effect of a fan, consequently increasing the power of such engines when used as radiators.

Where an engine d is provided having a water jacket d it is preferable to so mount the drum and locate the system of tubes that the drum in rotating assists the circulation in the said jacket. To efiect this objectthe drum in question may with advantage be mounted direotly in connection with the shaft so as to take the place more or less of a fly wheel, a construction especially'applicable where the apparatus is fitted to an internal combustion engine with a horizontal shaft (Z With this construction in order to prevent the siphonin of the water from the water jacket, w ich tends to take place at the stoppage of the motor, the said system of pipes is divided in the neighborhood of the inlet and outlet of. the aforesaid jacket. Again to insure an efficient circulation a pump, not shown, may be combined with the system of pipes or else (and this construction is equally feasible when the apparatus in question is only being used as a simple 'pump) an outlet similar to the inlet 7; in'the drum is prothe exit passage 6 so that the two effects just mentioned maybe obtained concurrently.

It is preferable to combine with a tube or tubes b and b contained in the interior of the drum a, pieces 6 and e which resemble gutters used in architecture so that if liquid tends to flow and drip along the exterior of the said tubes below these parts it is obliged to return to the drum. Battles e are also provided with the same object, on that part of the shaft on the inside of the drum a, in the case where drum hasa shaft which penetrates inside. The said drum is provided in addition with a supplem'entary tube b the orifice of which is preferably'directed oppositely to the direction of rotation of the drum. This is adapted to act as an overflow pipe, the aforesaid orifice being located at a distance from the periphery of the drumequal to that to which the inner-surface of the ring of liquid reaches from the aforesaid periphery so that when the drum is in rotation it contains the exact quantity of, liquid necessary for proper working. This addition is especially useful in cases where the drum is provided with a horizontal axle mounted directly in comi'ection with the motor so as to act as a radiator to the latter, as it does away with the necessity of an device for refilling it, this being effected supplying directly or indirectly to the d i'um all the liquid that can be stored therein the excess being immediately carried away through the supplementary tube bwhen the drum is rotating.

As will be readily understood the invention is in no way limited to the methods of v carrying it into effect which have been more particularly described but includes all modifications embodying the same principles.

What we claim and desire to secure by Letters Patent of the United States of of which comprises a large central a erture and a pair of fixed pipes extending t rough said aperture one for the admission of liquid which is under pressure and the other for the withdrawal of the liquid,these two pipes being divided before and after the overhead reservoir for the liquid with the special object of preventing the siphoning of the liquid from the reservoir when the rotation of the drum is stopped. I

2. In a centrifugal hydraulic engine, the combination of a rotary drum having an outer closed face and an inner face with .a central aperture, a shaft extending through the aperture in the inner face and secured to the outer face, and a. pair of fixed pipes also extending through the said aperture of the inner face and having reversely outwardly projected extremities, the one pipe cooperating with the outer portion of the drum adjacent to the outer face and serving as a liquid supply to the interior of the drum and its outlet extremity within the drum disposed in opposition to the direction of rotation of the drum, and the other pipe cooperating with the inner portion of the drum adjacent to the inner face and serving to withdraw the liquid from said drum.

3. In a centrifugal hydraulic engine, the combination of a rotary drum having an outer closed face and an inner face with a central aperture, a shaft extending through the aperture in the inner face and secured to the outer face, and a pair of fixed pipes also extending through the said aperture of the inner face and having reversely outwardly rojected extremities, the one pipe cooperatlng with the outer portion of the drum adjacent to the outer face and serving as a liquid supply to the interior'of'the drum and its outlet extremity within the drum disposed in opposition to the direction of rotation of the drum, and the other pipe cotiperating with the inner portion of the drum adjacent to the inner face and serving to withdraw the liquid from said drum, both pipes being provided with gutters surrounding the same within the drum.

4:. In a centrifugal hydraulic engine adapted for heating or cooling purposes, the combination of a rotary drum constructed of a metal having high conductibility and having an outer closed face and j through "the aperture and projecting at their free extremities in reverse directions toward the inner periphery of the drum, one of the pipes coiiperating with the outer portion of the drum and serving as the supply means therefor, and the other inner'face and having reversely outwardly projected extremities, the one plpe 0 "perating with the outer portion of the rum adjacent to the outer face and serving as a liquid supply to the interior of the drum and its outlet extremity within the drum disposed in opposition to the direction of rotation of the drum, and the other pipe codperating with the inner portion of the drum adjacent to the inner face andserving to withdraw the liquid from said drum, and a drain pipe also extending through the aperture in the inner face of the drum and cooperating with the inner portion of the latter and having the orifice in the free end within the drumfdisposed opposite to the direction of rotation of the drum.

6. Ina hydraulic engine of the circulating pump type; the combination of a rotary 'drum one at least of the" faces of which comprises a large central aperture a fixed pipe also extending through thesaid aperture withits extremity located at the distance from the periphery-of the drum at Whichthe surface of the ring of liquid formed within the drum during the rotation thereof is intended to come, so that the drum contains the exact quantity of liquid suitable for correct working and with the object of facilitating the refilling with liquid.

7. In a centrifugal hydraulic engine of the type. adapted to produce changes of temperature, the combination of a rotary drum having vanes projecting outwardly =from' the circumferential surface thereof' and 'extending around the drum to provide fans, thedrum having a large central aperture in one of its heads, and fixed pipes extending through the said aperture and projecting into the drum in reverse directions and toward the periphery of the latter.
